A machine for incorporating filament(s) into a fiber optic cable, e.g. a fly-off type strander (20). Strander (20) includes a frame (22) and a carriage (30) rotatably mounted to the frame. Carriage (30) includes filament packages (50) respectively mounted on fixed arbors (38) in protective barrels (33). For the prevention of snagging of the filaments on the packages, each barrel includes a respective filament guard (35) adjacent to or against which respective packages (50) are disposed. Each package (50) includes a respective filament tensioner (40) mounted to carriage (30) for tensioning a respective filament (52). As tensioners (40) are generally parallel to the axis of rotation of carriage (30), loosening or tightening of tensioner (40) during rotation of carriage (30) is avoided, whereby filaments (52) are firmly wrapped about a cable component at a controlled tension and an optimal speed.

Stranding machine for use in the manufacture of fiber optic cables

An optical cable or optical cable element and a method of manufacturing the same. The cable or cable element includes a tubular jacket containing a single optical fiber and a layer of loose tensile strength fibers applied without an intended lay surrounding the optical fiber. The tension applied to the tensile strength fibers during manufacturing does not exceed the tension applied during manufacturing to the optical fiber.
